That’s a good question, the PSU on Ambika is considerably different than Shruthi so in theory, the problem shouldnt exist. I thought someone did the yellow one and reported no problems. You will want to mount them on the front of the board though, not behind. They are about a third of the thickness.

Beware RS. I bought 2 green Vishay oleds and received 2 yellows. They were part numbered as Green and came in a anti-static bag labelled for Greens. The oleds inside were yellow with yellow part numbers on them. I didn’t return them as I just knew I’d get yellows back again.

and they work great. They are BRIGHT as all get out, there is some camera thing happening so it looks brighter and less green than in real life but I have a dark tinted gray window on top of mine to tame it. It’s almost too much without it
